Said anticorrosive agent is 6N/mm according to the overlapping tensile shear strength between the aluminium of JIS K6850 measurement
2More than.Should note; JIS K6850 (" TP of the overlapping tensile shear strength of tackiness agent-sticking material of rigidity quilt ") regulation is measured rigidity by the overlapping tensile shear strength of the mutual glue bond compound of sticking material through using the standard test sheet under adjusting of stipulating and test conditions.In the present invention, with aluminium sheet as rigidity by sticking material, and with this anticorrosive agent as being clipped in the adhesive layer between the aluminium sheet, and prepare test film thus.
If the overlapping tensile shear strength between the aluminium is less than 6N/mm
2Even then also be difficult to make the position such as the electrical connection section between wire conductor and the terminal component that require non-corrosibility to realize driving fit the anticorrosive agent fusion.Therefore, anticorrosive agent is difficult to obtain high anticorrosion ability.Overlapping tensile shear strength between the aluminium is preferably 7N/mm
2More than, more preferably 8N/mm
2More than.Because preferably this anticorrosive agent has sufficient adaptation, so the upper limit of the overlapping tensile shear strength between the aluminium does not receive special restriction.
Said anticorrosive agent is more than 100% according to the elongation (under 24 ℃ normal temperature) that ASTM D-1708 measures.
If said elongation is less than 100%, then on the electrical connection section between the position that requires non-corrosibility such as wire conductor and terminal component after the melt coated,, in said anticorrosive agent, produce shrinkage crack with the anticorrosive agent cooling and when solidifying.Water is immersed in the crackle thus, so said anticorrosive agent is difficult to obtain high anticorrosion ability.Said elongation is preferably more than 150%, more preferably more than 200%.Because preferably this anticorrosive agent has sufficient elongation, so the upper limit of said elongation does not receive special restriction.

2. this covered electric cable
The explanation of this covered electric cable then, is provided.
As shown in figs. 1 and 2, this covered electric cable 10 comprises covered electric cable 12, and it comprises wire conductor 18 and the isolator 20 that coats said wire conductor 18; Terminal component 14 with the said wire conductor that is connected to said covered electric cable 12 18 ends.
Metal wire preferably by copper, copper alloy, aluminium, duraluminum, or with a kind of the processing in these materials of various material platings.Wire rod as splicing thread is preferably processed by copper alloy, titanium, tungsten or stainless steel.Wire rod as organic fibre is preferably processed by KEVLAR.
The connection section 14c that terminal component 14 comprises (タ Block) shape that has pulling-on piece and is connected with relative terminal; Extend and be fastenedly connected electricwire conduit (the バ レ Le) 14a on wire conductor 18 ends of electric wire 12 and extend and be fastenedly connected the insulation thimble 14b on the terminal isolator 20 of covered electric cable 12 from the base end of connection section 14c from electricwire conduit 14a.
Said terminal component 14 (its basic component) is preferably become with copper by market brass, each Albatra metal-.Preferably use the part surface (for example tie point) or all surfaces of various metals such as tin, nickel and golden plating terminal component 14.
The part of wire conductor 18 is exposed at electrical connection section place between wire conductor 18 and terminal component 14.In this covered electric cable 10, cover the part of exposing with above-mentioned anticorrosive agent.Particularly; Anticorrosive agent film 16 stride across the connection section 14c of terminal component 14 base end and the border between wire conductor 18 front ends; Until the base end that covers connection section 14c; And stride across the insulation thimble 14b of terminal component 14 and the border between the isolator 20, until covering isolator 20.
Used anticorrosive agent can consider wire conductor 18 material and terminal component 14 material combination and in above-mentioned rerum natura scope, select.16 the thickness of filming to anticorrosive agent is suitably regulated; Yet said thickness is preferably 0.01mm to 0.1mm.16 thickness is too big if film, and then is difficult to terminal component 14 is inserted in the linker.On the other hand, if 16 the thickness of filming is too little, then anticorrosion ability is easy to descend.
If filming of forming 16 do not damage electrical connection, the back side of the back side of the pulling-on piece shape connection section 14c that then also preferably extends at the electricwire conduit 14a from terminal component 14, the back side of electricwire conduit 14a and insulation thimble 14b forms films 16.
When the coating anticorrosive agent, as long as anticorrosive agent can flow to the degree that can be coated with.Therefore, when the coating anticorrosive agent,, perhaps use appropriate solvent to make its liquefaction preferably with its suitable heating.Preferably carry out the coating of anticorrosive agent with drop method, coating method or extrusion molding.The Heating temperature that is used for said anticorrosive agent is preferably 150 to 250 ℃.
In order to improve thermotolerance and physical strength, preferably, make as required said film 16 crosslinked.The instance that is used for crosslinked method comprises heat cross-linking method, chemical crosslink technique, silane cross-linking method, electron irradiation crosslinking and ultraviolet-crosslinkable method, and it does not receive special restriction.
Because said anticorrosive agent mainly comprises the thermoplastic polyamide resin, so through adding thermal discharge flowability.Therefore, said anticorrosive agent has the character that is prone to coating, and this makes can accurately be applied to destination locations with anticorrosive agent with the mode of be sure oing.For example; Even the diameter at covered electric cable 12 is little (for example; 0.8mm) and the situation of the width of terminal component 14 little (being 0.64mm for example) at said pulling-on piece place under, also can be with the mode be sure of with anticorrosive agent close positioning and only be coated on the electrical connection section place between wire conductor 18 and the terminal component 14 accurately.
In addition because said anticorrosive agent is at the coating postcooling and solidify, so when operation, be not clamminess, but and extended immobilization to being coated with the place.Therefore, can keep anticorrosion ability for a long time.
3. this wire harness
The many covered electric cable harness cost wire harness that will comprise this covered electric cable 10 with terminal.In this wire harness, some in the covered electric cable that is comprised can be this covered electric cable 10, and the covered electric cable that is perhaps comprised can all be this covered electric cable 10.
In this wire harness, said covered electric cable can be used the band harness, perhaps can use outer package member such as pipe, corrugated tube and protector with its outer packaging.
This wire harness is applicable in vehicle such as automobile and connects up, and is specially adapted in cabin of paddling or vehicle interior, connect up.These places receive the heat and the influence of water easily, and therefore when wire harness being used for when connect up in these places, get rusty in easy electrical connection section place between wire conductor 18 and terminal component 14.Yet, use this wire harness can prevent effectively that the electrical connection section place between wire conductor 18 and terminal component 14 from getting rusty.
